In the xy coordinate plane, line L and line K intersect at the point (4,3). Is the product of their slopes negative?We have two lines: \(y_l=m_1x+b_1\) and \(y_k=m_2x+b_2\). The question: is \(m_1*m_2<0\)? Lines intersect at the point (4,3) > \(3=4m_1+b_1\) and \(3=4m_2+b_2\) (1) The product of the xintersects of lines L and K is positive. Now, one of the lines can intersect xaxis at 0<x<4 (positive slope) and another also at 0<x<4 (positive slope), so product of slopes also will be positive BUT it's also possible one line to intersect xaxis at 0<x<4 (positive slope) and another at x>4 (negative slope) and in this case product of slopes will be negative. Two different answers, hence not sufficient. But from this statement we can deduce the following: xintersect is value of \(x\) for \(y=0\) and equals to \(x=\frac{b}{m}\) > so \((\frac{b_1}{m_1})*(\frac{b_2}{m_2})>0\) > \(\frac{b_1b_2}{m_1m_2}>0\). (2) The product of the yintersects of lines L and K is negative. Now, one of the lines can intersect yaxis at 0<y<3 (positive slope) and another at y<0 (positive slope), so product of slopes will also be positive BUT it's also possible one line to intersect yaxis at y<0 (positive slope) and another at y>3 (negative slope) and in this case product of slopes will be negative. Two different answers, hence not sufficient. But from this statement we can deduce the following: yintercept is value of \(y\) for \(x=0\) and equals to \(y=b\) > \(b_1*b_2<0\). (1)+(2) \(\frac{b_1b_2}{m_1m_2}>0\) and \(b_1*b_2<0\). As numerator in \(\frac{b_1b_2}{m_1m_2}>0\) is negative, then denominator \(m_1m_2\) must also be negative. So \(m_1m_2<0\). Sufficient. Answer: C. In fact we arrived to the answer C, without using the info about the intersection point of the lines. So this info is not needed to get C. For more on coordinate geometry check the link in my signature. P.S. This question can be easily solved by drawing the lines without any calculations.

Can you tell me how did you decide y=0? Xintercept is the point where a line (a graph) crosses the xaxis. So it's the point on xaxis, any point on xaxis has ycoordinate equal to zero, which means that Xintercept is the point \((x,0)\)  the value of \(x\) when \(y=0\): \(y=mx+b\) > \(0=mx+b\) > \(x=\frac{b}{m}\). So Xintercept of a line \(y=mx+b\) is \(x=\frac{b}{m}\); Yintercept is the point where a line (a graph) crosses the yaxis. So it's the point on yaxis, any point on yaxis has xcoordinate equal to zero, which means that Yintercept is the point \((0,y)\)  the value of \(y\) when \(x=0\): \(y=mx+b\) > \(y=m*0+b\) > \(y=b\). So Yintercept of a line \(y=mx+b\) is \(y=b\). Check Coordinate Geometry chapter for more (link in my signature). Hope it's clear.

The equation of a line can be written as : \(\frac{x}{a} + \frac{y}{b} = 1\) Here a is the Xintercept and b is the Yintercept The slope of this line is b/a Let the lines be : \(\frac{x}{a_1} + \frac{y}{b_1} = 1\) \(\frac{x}{a_2} + \frac{y}{b_2} = 1\) We know both lines pass through (4,3) So we know that \(\frac{4}{a_1} + \frac{3}{b_1} = \frac{4}{a_2} + \frac{3}{b_2} = 1\) The information about (4,3) doesn't tell us much about the signs of a1,a2,b1,b2 Question is if Slope1*Slope2 =(b1 b2) / (a1 a2) < 0 (1) a1 * a2 > 0 Depends on the sign of b1*b2 (2) b1 * b2 < 0 Depends on the sign of a1*a2 (1) + (2) : Clearly sufficient to say yes. The slope product is always < 0.

under timed schedule, i considered using a quick graphical sketch and that helped. Let M1 and M2 represent the gradients of lines K and L (1) from sketch (i), M1*M2 < 0 from sketch (ii), M1*M2 > 0 INSUFFICIENT (2) from sketch (i), M1*M2 < 0 from sketch (iii), M1*M2 > 0 INSUFFICIENT Combining (1) and (2): ONLY sketch i) satisfies > SUFFICIENCY option C is therefore correct.

In the xycoordinate plant, line t and k intersect at (4,3). Is the product of their slopes negative? 1. Product of the x intercepts of the line t & k is positive 2. Product of the y intercepts of the line t & k is negative Sol: To draw a line with +ve slope through a point(x1, y1) on a 2D plane; draw two lines passing through the point perpendicular to each other with one line parallel to xaxis and the other parallel to yaxis(depicted by red lines in the images). These redlines make 4quadrants with origin(x1,y1). Any line that passes through this origin and lies on 1st and 3rd quadrant will have +ve slope. Any line passing through the point and lying on the 2nd and 4th quadrants will have negative slope. Attached images show two possible scenarios for St1 and St2 making the statements insufficient individually. Last image shows the only possible scenario for the lines, making both the statements sufficient together. St1: Insufficient. Attachment:

(1) So they both have +ve xintercept or ve x=intercept This is not sufficient, as can be seen from diagram, both can have +ve slope or 1 can have ve and 1 +ve slope (2) So they both intersect yaxis on different sides of XAxis This is also not sufficient, as can be seen from diagram, both can have +ve slope or 1 can have ve and 1 +ve slope (1) and (2) They are sufficient, as only the option with two lines on right of yaxis is possible. Hence products of slopes is negative. Answer  C

Calculate slope for L [(4,3) and (X1, 0)] and m [ (4,3) and (X2, 0)] such that X1*X2=+VE Similarly take Y1 and Y2. and calculate slope for L [(4,3) and (0, Y1)] and m [ (4,3) and (0, Y2)] such that Y1*Y2=VE Now combine these two statement and calculate slope for L [(0, Y1) and (X1, 0)] and m [ (0, Y2) and (X2, 0)] Slope of L*M = Y1/(X1)*Y2/(X2) = Y1*Y2/ X1*X2. Given that Y1*Y2= VE and X1*X2=+VE. Hence Slope of L*M = VE Answer C.

Let the lines be :
\(\frac{x}{a_1} + \frac{y}{b_1} = 1\) \(\frac{x}{a_2} + \frac{y}{b_2} = 1\)
We know both lines pass through (4,3) So we know that \(\frac{4}{a_1} + \frac{3}{b_1} = \frac{4}{a_2} + \frac{3}{b_2} = 1\) The information about (4,3) doesn't tell us much about the signs of a1,a2,b1,b2
Question is if Slope1*Slope2 =(b1 b2) / (a1 a2) < 0
(1) a1 * a2 > 0 Depends on the sign of b1*b2
(2) b1 * b2 < 0 Depends on the sign of a1*a2
(1) + (2) : Clearly sufficient to say yes. The slope product is always < 0. Did this way using the intercept form of a line. Have made an observation that using intercept equations in gmat questions significantly reduces the time to solve a question. Thanks. A thumb rule I use in coordinate geometry for lines: 1. Use intercept form x/a + y/b = 1  If intercepts are given, for area questions usually, for ladder against wall type questions, triangle questions2. Use slope form y=mx+c  when slope is implicit or explicitly stated in the question 3. Use one point slope form yy1=m(xx1)  when we know slope and line passes through a point4. Use 2 point form yy1/y2y1 = xx1/x2x1  when line passes through two points5. When all else fails we resort to pure algebra of a linear equation ax+by+c=0

.

If we modify the original condition and the question, the equation for a line that crosses (2,1) and (4,3) is y=x1. Then, if B(m,n), n=m1. There are, 2 variables (m and n) and 1 equation (n=m1). In order to match the number of variables to the number of equations, we need 1 equation. Since the condition 1) and the condition 2) each has 1 equation, there is high chance that D is the correct answer. Since 1)=2) (m,n)=(3,2), the answer is yes and the conditions are sufficient. The correct answer is D.

Can the question be solved the following way? Or, am I just lucky with the solution particular to this question?
Slope of a line = \(\frac{rise}{run}\) = \(\frac{yintercept}{xintercept}\)
With this in mind,
(1) The product of the xintercepts of lines \(l\) and \(k\) is positive
Translation:
\(\frac{y}{x}\) = \(+\) or \(\frac{y}{x}\) = \(\)
Insufficient
(2) The product of the yintercepts of lines \(l\) and \(k\) is negative
Translation:
\(\frac{y}{x}\) = \(+\) or \(\frac{y}{x}\) = \(\)
Insufficient
(1) & (2):
\(\frac{y}{x}\) = \(\) is the only answer in common and therefore, sufficient.
Please advise,
